What are the advantages of silk?

1, comfortable. Because silk fabric is made of silk and silk is made of protein fiber, it has good biocompatibility with human body and smooth surface. The friction coefficient of various fibers is the lowest, only 7.4%.

2. Absorb and release water. Silk is rich in hydrophilic groups such as amino (-CHNH) cellulose and amino (-NH2), and because of its porosity, it is easy to divide water, so it can absorb water or water supply in the air and retain a small amount of water.

3. Good insulation. It is insulated by fibers in a porous structure. Among silk fibers, there are many very fine fibers. Therefore, the appearance of 38% solid silk is actually hollow, and there is a big gap to prevent the heat distribution of air, so that silk has good thermal insulation.

4, heat-resistant, sound-absorbing and dustproof. Silk fabrics have large porosity and good sound absorption, and can absorb harmful gases, dust and microorganisms. In addition, silk is also a kind of heat-resistant fiber. As the raw material of interior decoration, silk fiber can not only play the role of sound insulation, dust prevention, thermal effect and flame retardant.

5, anti-UV. Tryptophan and tyrosine in silk protein can absorb ultraviolet rays, so silk has good anti-ultraviolet ability. Ultraviolet rays do great harm to human skin. Of course, silk will undergo chemical changes after absorbing ultraviolet rays, so it is easy to turn yellow under the irradiation of the sun.

6. Silk fabrics also have excellent dyeing properties, which can be dyed with acid, neutral, direct, reactive, cationic, reducing, soluble reducing and insoluble azo dyes. However, silk is easy to be damaged in alkaline medium, so acid dyes are mainly used, supplemented by neutral, direct and reactive dyes.
